EURORACK MX2004A
4.5 2-track input and output
Input
A 2-track input, on RCA connectors / , provides easy connection to DAT and other professional or
semi-professional audio equipment.
The 2-track input is primarily for auditioning mix playback from tape. The switch 2 TK routes this signal to
the monitors and/or phones.
However, it can also be routed to the main mix via the switch 2 TK TO MIX and will act as an additional
input for tape playback, MIDI instruments etc. Here switch should be disengaged, or you will be listening
to the 2-track signal twice over!
With depressed you have another stereo line input available to the mix, useful e.g. for adding the output of
a second EURORACK or a BEHRINGER ULTRALINK PRO MX882 to your mix.
Output
The main mix output is delivered by XLR connectors and TRS connectors on the back panel as well
as by RCA connectors on the front .
Level is ultimately determined by a pair of precision faders .
Although the 2-track output is primarily designed for recording, it can also be used as a PA feed, or as a send
to the input of your sampler. Depressing on the rear panel will lower the level at the XLR connectors by
20 dB.
4.6 Monitoring
Though most of you will want to audition the main mix most of the time there are exceptions. These
include the Alt 3-4 bus and 2-track playback .
A single stereo volume control sends the level to the headphones and main monitors .
If you want to audition external sources very often, you could connect a hi-fi pre-amp (or tape out) to your
2-track input, allowing you to monitor a variety of extra sources such as vinyl, cassette, CD etc.
4.7 Alt 3-4 output
By depressing the MUTE/ALT 3-4 button a channel’s output will be routed to the Alt 3-4 output instead of
the main mix.
Level to the Alt 3-4 outputs (phone connectors on the back panel) is adjusted by . Use to have the
signal PFL-ed ( and up).
Alt 3-4 is likely to bewilder newcomers. We want to illustrate how this feature may be used most effectively.
Subgroups are commonly used as a mixing aid both live and in the studio, e.g. to combine the outputs from all
drum channels onto just 1 or 2 submaster faders. They are also used to route to multitrack recorders (see also
sections 9.2 and 12.3).
There are no fully-fledged subgroups on the MX2004A. However, the Alt 3-4 bus offers you a second indepen-
dent stereo submix with its own submaster stereo fader .
E.g.: If you want to generate two mono subgroups in addition to the normal main mix stereo bus, patch Alt 3-4
outs back into two mono channels, and use these as Subgroup masters (the subgroup return channels must
not be routed to the Alt 3-4 bus themselves, as this would constitute a feedback loop). Engaging mute on any
input channel routes to the Alt 3-4 bus. Channel pan now selects between Alt 3-4 outputs (left = 3, right = 4).
+ Subgroups can be mixes of several channels of sound: don’t be surprised if, once you have set
up the input gain correctly, the submaster faders are set higher than “normal” channels.
Remember that when Alt 3-4 is in use, you do not have a channel mute facility on your desk: you will have to
pull down the fader to silence any channel.
